Thanks for reading. I have an LPAR on a P570 that has AIX 6.1.0.0. I created a mksysb file and would like to create a bootable DVD from the file. When I try to do this with smitty or the mkdvd command I get an error that /mkcd/cd_fs needs a little more than 3GB of space. The command df -g /mkcd/cd_fs shows that it has 1 GB free. I did the command chfs -a size=+4G /mkcd/cd_fs and received a message stating that it completed successfully. When I tried creating the dvd again I got the same message /mkcd/cd_fs needs 3GB more space. I looked at df -g again and it still showed as 1 GB free. What am I doing wrong?

lsvgfs rootvg shows that /mkcd/cd_fs is on the rootvg.

Hi,

What do the following commands show?
lsfs /mkcd/cd_fs
lslv <lv_name>

The LV STATE of closed/syncd indicates it's not mounted.

Have you definitely mounted the filesystem? (mount /mkcd/cd_fs)
It also looks to be about 22GB now. How many times have you run the "chfs -a size=+4G /mkcd/cd_fs" command?

No, I haven't done that command. I did the chfs command several times. Should I do mount /mkcd/cd_fs?

First clear up the mount point - the folder /mkcd/cd_fs - remove everything in there that you do not need as it will be hidden once you mount the new filesystem.

If you need to (to save space in rootvg for other purposes) reduce the size of the new filesystem from 22GB to, say 5GB:
chfs -a size=5G /mkcd/cd_fs
(Note NOT +5G)

Now mount the filesystem
mount /mkcd/cd_fs

And check with
df -g /mkcd/cd_fs

It should now show as 5GB, and be big enough for your dvd ISO.

I tried setting the size instead of increasing the size once with chfs but I got an error:

chfs: 0506-908 Cannot reduce size of file system

My mistake... you have a JFS filesystem; reduction only works with JFS2.

You can either remove it and create again at the correct size, or work with it at 22GB, and as it is for temporary use only, delete it when you've got your ISO off.

Decide which, and then go to the mount command...

If I try to keep it at 22GB I still get:

yet my mksysb file is only

df -g /mkcd/cd_fs

Thanks...

The filesystem still isn't mounted...

Was there any output from
mount /mkcd/cd_fs
?

After I did the mount command it worked. Thanks!
